The high brightness temperature of B0529+483 revealed by RadioAstron and implications for interstellar scattering
S. V. Pilipenko, Y. Y. Kovalev, A. S. Andrianov +22
The high brightness temperatures, K, detected in several active galactic nuclei by RadioAstron space VLBI observations challenge theoretical limits. R…
Probing the innermost regions of AGN jets and their magnetic fields with RadioAstron II. Observations of 3C 273 at minimum activity
G. Bruni, J. L. Gómez, C. Casadio +18
RadioAstron is a 10 m orbiting radio telescope mounted on the Spektr-R satellite, launched in 2011, performing Space Very Long Baseline Interferometry (SVLBI) observations supporte…
PKS 1954-388: RadioAstron Detection on 80,000 km Baselines and Multiwavelength Observations
P. G. Edwards, Y. Y. Kovalev, R. Ojha +24
We present results from a multiwavelength study of the blazar PKS 1954-388 at radio, UV, X-ray, and gamma-ray energies. A RadioAstron observation at 1.66 GHz in June 2012 resulted…
RadioAstron Observations of the Quasar 3C273: a Challenge to the Brightness Temperature Limit
Y. Y. Kovalev, N. S. Kardashev, K. I. Kellermann +17
Inverse Compton cooling limits the brightness temperature of the radiating plasma to a maximum of K. Relativistic boosting can increase its observed value, but apparent…
Extreme Brightness Temperatures and Refractive Substructure in 3C273 with RadioAstron
Michael D. Johnson, Yuri Y. Kovalev, Carl R. Gwinn +8
Earth-space interferometry with RadioAstron provides the highest direct angular resolution ever achieved in astronomy at any wavelength. RadioAstron detections of the classic quasa…
